Compare Journalling, Meditation, and Exercise as Daily Wellbeing Practices

You keep being told to journal, meditate and exercise, and you have time for maybe one. This sets a wellbeing researcher onto comparing all three: what each actually does, who it suits, and where the evidence is strongest. You get back a clear basis for choosing where your limited minutes go, instead of guilt about the two you skipped.

<context>
Journalling, meditation, and exercise are three of the most widely recommended daily wellbeing practices. Each has a strong evidence base but they suit different people and serve different functions. Understanding how they differ helps people choose where to invest their limited time.
